IMPROVEMENT IN VEHICLE-SPRINGS.

Specification forming part of Letters Patent No. 149,483, dated April 7,1874; application led March 9, 1874.

To all whom it may concern:

Be it known that I, ORLANDO JnNNnss, of Alton, in the county of Belknapand State of- New Hampshire, have invented certain new and usefulImprovements in Springs; and I do hereby declare the following to be afull, clear, andA eXact description .of the invention, such as willenable others skilled in the art to which it pertains to make and useit, refer- Vence being had to thc accompanying drawings,

which form part of this specification.

The nature of my invention. relates to an improvement in springs forvehicles; and it consists in an independent spring, which can be readilyapplied to vehicles of all kinds, and which iscomposed of a top and baseplate, connected together by a number of rods, around which are placedcoiled springs, the rods being made to move freely back and forththrough the base-plate, whenever pressure is applied upon either plate,so as to bring the pressure upon the springs.v

The accompanying drawings represent my invention.

a c represent two fiat plates, of unequal size, which are connectedtogether by rods d of suitable length, around which rods areplaced'coiled springs e. At their upper ends the rods, which may be ofany desired number, are screwed or otherwise rigidly secured to the topplate a, while the lower ends of the rods pass down through thebase-plate c, through which they freely play, and are enlarged below theplate, so as to prevent the plate from slipping off. The base-plate ismade larger than the top plate, so that it will rest upon the top of anaxle, or lower part of the spring, and allow the lower ends of the rodsto pass freely down their sides whenever a sufficient force is broughtupon either plate to compress the springs.

is placed in between the two parts of the springs, soas to ease thepressure upon them. Where the springs are placedupon the sides of thebody, my device will be placed upon the tops of the axles, and supportone or both ends of the body. l

Each of the two plates has a hole made through its center to receive astud or bolt of any kind, so as to hold it in position; and, as there isno need of nuts, the device can be applied or removed from a vehicle ina moment.

Having thus described my invention, I claim- As an independentattachment to vehicles, a spring consisting of the top and base plates ac, rods d, which have a vertical play through one of the plates, and thecoiled springs e, the parts being combined substantially as set forth.

In testimony that I claim the foregoingI have hereunto set my hand this3d day of March, 1874.
